This creamy, cozy Marry Me Chicken Soup has all the viral flavors of the original dish—sun-dried tomatoes, garlic, Parmesan, Italian herbs—but in a rich, comforting, one-pot soup with chicken thighs, bacon, and pillowy 5-cheese tortellini. It’s elegant enough for date night and easy enough for weeknights.
Cook the diced bacon in a large Dutch oven over medium heat until crispy, then remove with a slotted spoon and leave 1–2 tablespoons of bacon fat in the pot.
Season the chicken thighs with salt, pepper, and Italian herbs, then sear them in the hot bacon fat for about 3–4 minutes per side. Remove the chicken from the pot and set aside to cool slightly before dicing or shredding.
Add butter to the pot and sauté the diced onion until softened. Stir in the garlic and cook until fragrant, then mix in the tomato paste and let it toast for 1–2 minutes. Add the sun-dried tomatoes and stir well to coat.
Pour in the chicken broth, heavy cream, bouillon, red pepper flakes, and Italian herbs, then return the chicken to the pot. Bring everything to a gentle simmer. Add the tortellini and cook until tender according to package directions, then stir in the baby spinach until just wilted.
Turn off the heat and finish the soup with the crisp bacon, grated Parmesan, and a squeeze of lemon if desired. Taste and adjust seasoning before serving.
